The present study has investigated the synthesis of copper nanoparticles via copper dismutation reaction in an aqueous solution and ambient conditions. Copper (II) chloride hydrate ( ), sodium oleate (SO), sodium chloride (NaCl) and ethylene diamine (EN) have been used as copper (I, II) ions source, surfactant, chloride ions supplier and ligand, respectively. Also, an amount of hydrochloric aci...

Drosophila alcohol dehydrogenase (Adh) catalyses the oxidation of both alcohols and aldehydes. In the latter case, the oxidation is followed by a reduction of the aldehyde, i.e. a dismutation reaction. At high pH, dismutation is accompanied by a small release of NADH, which is not observed at neutral pH. Previously it has been emphasized that kinetic coefficients obtained by measuring the incre...

The recent assertion of J. Diguiseppi and I. Fridovich (1980, Arch. Biochem. Biophgs. 203,145-150) that Fe-EDTA does not catalyze superoxide dismutation is disputed. By directly observing superoxide generated during pulse radiolysis, we have confirmed the results of a previous study (G. J. McClune, J. A. Fee, G. A. McClusky, and J. T. Groves, 1977, J. Amer. Chem. Sot 99, 5220-5222) which conclu...

Currently, the most common method of silane synthesis for electronics and photovoltaics is trichlorosilane (TS) dismutation. TS dismutation proceeds in form a reactions cascade, therefore its study both practical scientific interest. The results calculating equilibrium composition reaction mixture vapor phase based on literature data from various sources were not reliable. Therefore, dependence...

We have previously shown that the phosphorylation of vitamin B1 to cocarboxylase by an atiozymase preparation is dependent upon the presence of hexosediphosphate and certain heat-stable factors contained in boiled tissue extracts (1). Our results further indicated that this phosphorylation was completely inhibited by 0.0025 to 0.005 M sodium iodoacetate, and that the addition of 0.04 M sodium f...

An up to 18-fold increase of the turnover frequency (TOF) in the catalase-like hydrogen peroxide dismutation reaction is observed by incorporation of substituents in the β-position of xanthene-modified iron corroles.

A lag phase in the spectrophotometric assay progress curve of aldehyde oxidation by HL-ADH was observed and characterised. The aldehyde oxidation and aldehyde dismutation reactions were shown to be related, and a mechanism to explain net aldehyde oxidation was proposed. The spectrophotometric assay was shown to be unsuitable for measurement of kinetic parameters for aldehyde oxidation by HL-ADH...

A complete chemical balance which demonstrates the occurrence of Reaction 3 has now been obtained. There is no reaction in the absence of either TPN, .Zwischenferment, or “malic” enzyme. The rate of reaction is proportional to the concentration of “malic” enzyme and to the CO* tension. It is also possible to couple the isocitric dehydrogenase-oxalosuccinic carboxylase system (2) with “malic” en...

Reaction 1 requires DPN and manganous ions. It is specific for Imalic acid; d-malic acid is inactive. TPN cannot replace DPN. Reaction 2 requires the presence of manganous ions. The evidence presented below supports the view that Reaction 1 is a DPN-linked dismutation between Z-malate and pyruvate, resulting from the interaction of lactic dehydrogenase with a DPN-specific “malic” enzyme as show...
